Nexen Petroleum’s Rochelle gas condensate field in the UK North Sea is back producing from both wells after mechanical difficulties and a hydrocarbon release on the Scott platform.
Junior partner Endeavour International said West Rochelle W1 well had now been returned to production.
“Both West and East Rochelle wells are now flowing together and Rochelle production will be optimized between the two wells in the coming days,” the explorer said, adding it may increase its quarterly guidance after stable rates emerge.
The West Rochelle 1 well was originally brought online last autumn but was shut in earlier this year as part of the final start-up work on the East Rochelle E2 well.
A problem with the manifold valve was discovered in February during work to bring on stream the E2 well that led to both wells being shut in.
Subsequently, as Upstream reported last month, a hydrocarbon release on Nexen Petroleum’s Scott platform caused Rochelle and two other fields to be shut in for a month.
China National Offshore Oil Corporation-owned Nexen Petroleum holds a 41% operatorship stake in the field, which is located in blocks 15/26b, 15/26c and 15/27, with partners Endeavour International on 44% and Premier Oil on 15%.
